PackUV: Video-Native Representations For Streaming 4D Scenes

A series of images showing how PackUV uses Gaussian UV fitting and produces one representation with all attributes that's 100% video-codec compatible

Imagine watching a concert not from a fixed camera angle, but from any angle. The catch? Volumetric video is incredibly hard to store and stream, and you can have the most photorealistic 4D scene in the world, but if you can't get it to a viewer efficiently, it's stuck in a lab. Our work, PackUV, tackles exactly this problem.
